IM PROVEM ENT IN STREET-LANTERNS.

Specification forming part of Letters Patent N0. 57,148, dated August14, 1866.

To all whom it 'may concern.'

Be it known that I, BENJAMIN A. JOHNSON, of Jeffersonville, in thecounty of Clarke and State of Indiana, have invented a new and usefulImprovement in Street-Lanterns; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art t0 make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

The present invention consists, principally, in forming the bottom orbase portion ot' a streetlantern of cast-iron or other suitable metaland the body of sheet metal, whether tin or galvanized iron or othersuitable sheet metal, whereby sufficient strength and lightness inweight are secured, in connection with durability and convenience ofhandling, and also the expense of the lantern greatly lessened; and italso consists in combining with the bottom or base portion of thelantern a novel mode of' securing the lantern to its post, as will behereinafter fully explained.

In the accompanying plate of drawings my improvementsin street-lanternsare illustrated, Figure 'l being an elevation of one side ofthe lanternmade according thereto, and Fig. 2 a horizontal section taken in theplane of the line x x, Fig. l.

Similar letters of reference indica-te like parts.

A in the drawings represents the bottom or base portion of the lantern,which is to be made of cast-iron or other suitable metal, and of theordinary form. To and around the sides of this base A of the lantern itsbody-frame B is to be secured, which body-frame I make of sheet-tin orgalvanized iron, or any other suitable sheet Inetal, and of the generalform and style adopted for street-lanterns, or of any other desired andsuitable style, the several sides of this bodyframe B having glasses C Cinserted in it for the purpose of shedding or diffusing the lightimparted by the lamp or each of its corners and extending toward itscenter, is secured a concentric sleeve or ferrule, F, in a verticalposition, and with Its upper end in a plane a short distance below theVlantern-base A. This ferrule or sleeve F is made of a tapering shapeupon its inside, and is provided with a series of projecting lugs, G, atsuitable points around its outside to receive the arms E, by which it issecured to the lantern-base A. By this ferrule or sleeve the lantern issecured to and over the upper end of its post or other stand or supportprovided for its reception, it being only necessary that such postshould be so formed at its upper end as to receive the said ferrule andhold it at the desired height.

From the above description it is plain to be seen that, by constructingthe lantern in the manner explained, not only is sufficient strengthobtained, but great lightness in weight, thus rendering the lantern notonly durable but convenient to handle, the mode of securing it to itspost or support being also exceedingly simple, convenient, and ecient. Iclaim as new and desire to secure by Letters Patentl. A street-lanternhaving its base A made of cast-iron or other suitable metal and its bodyB of sheet-tin or other suitable sheet metal, substantially asdescribed, and for the purpose specified.

2. The ferrule or sleeve F, secured to the bottom or base A of astreet-lantern by means of arms E, substantially as described.
